Energy Saving And Unit Safety Protection Tips

• Do not cover or restrict the airflow from the outlet or inlet grills.
• For maximum performance the distance between the unit and a wall or objects should be at least 19.5 inch.
• While in operation, ensure that the level of the water tank does not exceed MAX and does not fall below MIN.
• Keep the filters clean. Under normal conditions, filters should only need cleaning once every three weeks (approximately). Since the filters remove airborne particles, more frequent cleaning may be necessary, depending on the air quality.
• In order to achieve maximum efficiency the unit should be placed near an open door or window.

Evaporative Air Coolers work with an evaporative cooling mechanism which requires cross ventilation.

• This unit will lose efficiency if the relative humidity within the room exceeds 60%.
• The ambient operating temperature range is from 41°F to 104°F.
• If used in low temperatures (as a humidifier) it is recommended to fill the water tank with warm (but not hot) water.

Operation

The air cooler cools the air by means of evaporation. When water evaporates into the air, the result is a mixture of air and water molecules. This chemical change requires heat which is taken from the water molecules, resulting in a spot cooling effect.

Evaporative Air Cooling Mechanism:

A diagram shows water being pumped through honeycomb cooling media, where it evaporates and cools the air. Warm, dry air enters the unit, and cool, humid air exits.

The recommended relative humidity for optimum operation is 60% or lower. A drier climate makes for more noticeable cooling.

The evaporative air cooler should not be used in enclosed or sealed spaces. It must be kept level and there must be water in the tank. Doors and windows should be open to allow free air flow. The evaporative air cooler works best when placed near an open window / air current.

The evaporative air cooler can also be used to humidify dry environments (during cool weather). To be used for humidification the windows and doors should be closed to allow the humidified air to accumulate. The evaporative air cooler is not an air conditioner as it does not use a compressor or refrigerant. It should not be expected to cool as effectively as a refrigerated air conditioner.

When the product is used for the first time the Honeycomb cooling media will have an odour, this should dissipate within a week of use.

Parts List

• Control Panel
• Handle
• Top Water Tank
• LED Display
• Air Outlet
• Water Level Window
• Casters
• Particle Filter
• Honeycomb Filter

Installation

This unit can easily be moved from one room to another. While moving the unit please note that it must always be kept upright and then placed on an even surface.

• Remove all packaging – while keeping the air cooler in a vertical position.
• Make sure that all parts are present and that the unit is assembled correctly - including the wheels (these need to be pushed into place on the base of the unit).
• Water tank: Fill the top water tank with water ensuring that water tank does not to go above the MAX level visible on the front of the unit.
• When cooling/humidifying, the water level must not be lower than the MIN water line.
• If you want to increase the cooling effect, you can put ice or the charged ice packs into either water tank, but be sure that by adding ice or ice packs the water level does not go over the MAX limit. Empty some water if necessary via the drain on the back of the unit.
• Make sure that the filter pad is properly inserted into the back of the unit.
• Connect the power plug to a working socket, and then press the power button.

Please note: When the unit is plugged in, the appliance will go through a diagnostic process to ensure it is ready for operation. While this is carried out the lights on the front will flash.

Ice Box

The ice box can absorb the heat in the water, which in turn can lower the temperature of the water tank. This can make the air flow cooler.

• Remove the ice box and put it in the freezer until it is totally frozen.
• Put the frozen ice box into the top water tank.

Cleaning and Maintenance

ATTENTION: Please shut off the unit and unplug from the mains before cleaning or performing any maintenance.

Cleaning the Surface

Clean the plastic housing with a duster or a soft wet cloth. Do not use chemical solvents (such as benzene, alcohol or gasoline) as they may cause irreversible damage. Make sure no water enters the control panel.

Cleaning the Water Tank

Unplug the power cord and remove the honeycomb filter bracket. With a cloth (dipped in a mild detergent), wipe the water tank. Before using the unit, the tank should be rinsed by filling the tank and allowing it to drain through the drain port.

Draining the water reservoir and refilling with fresh water at least once a week will help reduce any mineral deposits and keep the filters clean. Do not run the unit in Humidify mode with stale water in the tank. We recommend emptying the tank and refilling it with fresh water if water has been standing in the tank for an extended period of time.

Maintaining and Changing the Honeycomb Filter Pads

The appliance is supplied with Honeycomb cooling / filters pads. The cleaning frequency for the Honeycomb filter depends on local air and water conditions. In areas where the mineral content of water is high (hard water), mineral deposits may build up on the honeycomb cooling filter and restrict air flow. If mineral deposits remain on the Honeycomb pads, the filter should be removed and washed under fresh water. For a deeper clean a mild detergent should be used with a soft brush. Once cleaned the filter should be rinsed in clean water before leaving to dry.

We recommend cleaning the honeycomb filter at least every two months, depending on your needs.

For best results, allow the honeycomb filter to dry after each use by turning off the COOL function and running the unit as a fan for 15 minutes before turning the unit off.

End of Season Maintenance

1. Empty the tank and clean it following the instructions above.
2. Clean the Honeycomb pad.
3. Store the Icepack in the water tank.
4. Cover the unit and keep it in a dry place.

Trouble Shooting
